Rare wild animals under protection, including the red-crowned crane, are increasingly choosing to settle at Qarhan Salt Lake near Golmud City in Qinghai Province in winter thanks to an improved ecological environment. At an elevation of 2,670 meters, the lake stretches 160 kilometers from east to west, and 20-40 kilometers from south to north. It is rich in salt, potassium resources and other minerals.
